M68k gas from current tree

Using the current OpenBSD source tree, I have compiled gcc and binutils
for m68k-unknown-openbsd2.0. With this I am having trouble compiling
lib/csu/m68k/crt0.c. as complains on the lines:
bcc 1f
and
1: movel a7@, a0
this all seems to work ok with my m68k system created from the 2.0
tar balls. Although the as from the tar file reports
GNU assembler version 1.92.3, NetBSD $Revision: 1.1.1.1 $
and mine says:
GNU assembler version cygnus-2.7.1 (m68k-unknown-openbsd2.0), using BFD version cygnus-2.7.1
Can anyone give me any pointers on this? Am I supposed to be using
a different version of the tools?
Thanks,
Gwen
